  3. 3. Palladium(II)-Catalysed Heck and Addition Reactions Exploring Decarboxylative and Desulfitative Processes

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Bobo Skillinghaug; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Palladium; catalysis; palladium II catalysis; synthesis; Heck; carboxylic acid; sulfinic acid; sodium sulfinate; nitrile; styrene; ketone; aryl ketone; electrospray ionization mass spectrometry; density functional theory; microwave heating; continuous flow; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : Palladium complexes have the ability to catalyse cross-coupling of two organic moieties through the formation of transient metal-carbon bonds, thus bringing them closer to each other to facilitate the formation of a new bond. Palladium-catalysed coupling reactions are one of the most important carbon-carbon forming reactions available to organic chemists and many of these reactions rely on the reactivity of aryl-palladium complexes.

  5. 5. Catalytic Functionalization of Allylic Substrates by Palladium Pincer Complexes

    University dissertation from Stockholm : Department of Organic Chemistry, Stockholm University

    Author : Nicklas Selander; Stockholms universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Catalysis; Palladium; Pincer Complex; Boron; Multicomponent Reaction; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi; organisk kemi; Organic Chemistry;

    Abstract : This thesis is based on the development of novel catalytic reactions for the synthesis and application of organometallic reagents. The main focus is directed towards organoboronate derivatives. We developed an efficient procedure for converting allylic alcohols to the corresponding allylboronates using palladium pincer complexes as catalysts. READ MORE
